SOAP: Load existing SOAP message to SOAP client
To load an existing SOAP message into an instance of TElXMLSOAPClient component, you need to use its LoadMessage() method. This method lets you load the message from file (not on all platforms), from stream or from the instance of TElXMLDOMDocument class.
C#:
TElXMLSOAPClient SOAPClient = new TElXMLSOAPClient(null);
SOAPClient.LoadMessage("filename.xml");
// send message ...
Delphi:
SOAPClient := TElXMLSOAPClient.Create(nil);
SOAPClient.LoadMessage('filename.xml');
// send message ...
After the message is loaded, it can be signed.
